Terrific Item!

Its the bomb! Hi reliability!
Definately a good security device.
Plan to add more sensors. I have three now.
***** out of 5 stars.
PS:
Several of the alarm tones are kind of dorky. Can you make them a little cooler?

Guard Mine, Guardline

The Guardline sensor is easy to set up and use. I was able to be up and running within 5 minutes. The system is easy to install. One thing I recommend is NOT to use batteries for the receiver. I recommend purchasing a plug in. The receiver eats up batteries quickly.
